[infra] Add Bazel rules for codecs. This ports the third_party BUILD.gn files related to codecs (with a best-effort on arm/SIMD stuff). This includes: - libpng - libjpeg-turbo - libwebp - wuffs (gif) - libgifcodec - dng_sdk and piex (raw codec) This expands the string_flag_with_values macro to allow multiple values to be set at once. This was added in Bazel 5.0.0, however the latest pre-release version of that has a bug [1] which slows down compilation dramatically. This was fixed at ToT, but not released. As a result, I started using the Bazel 6 pre-release (via bazelisk). The macro select_multi makes writing select() where multiple elements could be on possible/easier. One can try compiling certain codecs by running: bazel build :skia-core --config clang --include_codec=raw_codec --include_codec=png_codec Suggested Review Order: - bazel/macros.bzl - bazel/common_config_settings/defs.bzl and its BUILD.bazel to see how the codec options are defined. - BUILD.bazel to see how the codec settings are used. - src/codec/BUILD.bazel to see the inclusion of Skia files to deal with specific codecs. - third_party/BUILD.bazel (while referencing the corresponding BUILD.gn files, such as third_party/libwebp/BUILD.gn) - Everything else.
